First off, "... Umarex Browning Buck Mark CO2 Air Pistol ... fires up to six rounds before needing to be reloaded..." is WRONG. This is a single shot, break action, spring-pneumatic pellet pistol. The overall size is 12 x 5-1/2 inches with a weight of 24.4 ounces (about 1-1/2 pounds). It has been made to resemble the original Browning Buckmark URX pistol that fires 0.22 caliber long-rifle gun-powder cartridges but this replica uses 0.177 caliber airgun pellets. The 5.25 inch long fully, rifled barrel makes it a good low powered pistol for indoor target practice out to about 10 meters.

The rear sight is adjustable for both windage and elevation but they are poor quality and my eyes are getting weak. A inexpensive reflex sight can be mounted on the 5 inch long weaver (the notches do NOT conform to the MIL-STD-1913 standard) rail to remedy these problems "¦ but it should be capable of withstanding the shock of the spring action firing mechanism (I had to 'super glue' the mirror in place after it shook loose). The front sight is removal but this is a molded plastic piece that also serves to position the recessed metal barrel inside the plastic barrel shroud. Note: the most detracting aesthetic feature of this gun is that Umarex made no effort to remove the 'mold' lines from the plastic barrel shroud.

This break action cocking system requires less that 20 pounds of force making it one of the easiest spring action pellet pistols to cock. There is also a safety that engages each time the pistol is cocked. The claimed 320-360 feet per second muzzle velocity has been reported somewhat greater depending on the particular example tested as well as a variance between different pellets. One of its better features is that it will accept any 0.177 caliber pellet made but the heavier 15-20 grain pellets will perform poorly. Personally I have settled on using because they are cheap and work well in this gun.

The worst thing about this gun is the shameful, horrible, heavy trigger pull. There is very little danger of this gun firing by accident. The sear can be polished a bit but other than that there is very little that can be done. Umarex should seriously consider a redesign of the trigger mechanism. Just moving the pivot point a bit would make all the difference in the world. They lose one star because of the trigger.

I have a large collection of air pistols, and this Umarex Browning Buck Mark is one of my favorites for target practice. It is by no means a powerful pistol, it shoots lead 7 grain pellets at about 320fps, but the tradeoff you make in power is made up for with accuracy, quietness and ease of cocking effort. The break barrel cocking effort is about 20 lbs, which is significantly less effort than my Beeman P17. My 10 yr old son cannot use the Beeman P17 due to the large effort needed to compress the piston; however, he is able to handle this gun without any significant problems. Also unlike my Beeman P17, there have (so far) been no mechanical flaws/defects with this gun. It feels quite solid in the hand and well balanced. The grip is rubberized and the barrel is housed in some type of synthetic plastic; however, it does not feel cheap at all. The gun is a lot quieter than my P17 as well but has less power.

This gun is also very accurate. I've put about 500 rounds through it and am consistently getting 0.75" groups at 15 ft. The rear site is adjustable for windage and elevation and the front site is non-adjustable. Be aware that unlike many other pellet guns that use dovetail mounts, this one instead uses a weaver/picatinny style mount.

The only thing I don't like about this gun (and the reason I deducted a star) is the terrible trigger. Compared to my P17, this single-stage trigger feels significantly harder to pull (around 6lbs) and is not crisp and clean like the P17. In fact, after 100 rounds, my finger was a bit sore from all the pulling. It takes a lot of effort to keep the gun steady while pulling the trigger. The trigger is non-adjustable and it looks like I'll just have to learn to live with the poor trigger.

I will try not to repeat too much of what others have said but, if you think about it, hearing the same positive or negative in a review is great information. It tells you if the product in question has a common pro or con or a rare one. That being said, I am basing my review largely in comparison to the Beeman P17 because I feel these two guns share a lot in common as far as the basic concept of what they are all about.

Weight and Balance - I am going by feel here, not statistics. They feel about the same in hand, but the Beeman P17 seems better balanced and "feels" lighter. That being said, one did not wow me over the other.

Power - Obviously the Beeman P17 is more powerful but not powerful enough to matter. Both fall into the "plinking" category so FPS, in my mind, doesn't matter. I have seen plenty of chrony tests that put the Beeman P17 between 370-405 and the Browning Buck Mark between 300-325 depending on the pellets you are firing. When you are plinking, it does not matter.

Build quality - Browning wins easily. I had to spend some time trimming up sharp plastic from the grip, scope rail, and from the vents near the muzzle on the Beeman P17 and this was a brand new gun sealed in that awful plastic beast of a package that companies love to use. Even after my efforts, there are still some sharp points which is not much fun on a gun that you have to cock which means additional handling compared to CO2 guns. Also, there is a known defect of the P17 so I, like many, disassembled the piston to sand inside, so the rubber ring around it doesn't get worn out quickly. Luckily, mine was smooth as can be but after seeing the lack of effort they put into the outside, I was compelled to check. Again, the Browning was smooth, fit, and finished.

Accuracy and trigger - The Beeman is more accurate out of the box, but the Browning is about as good with some practice and tuning. Your can get 1-2" groups easily without taking it too seriously. Remember...this is supposed to be fun. Beeman P17 trigger is lighter and better in my opinion but the Browning is fine just not as good and less finesse to it.

Cocking and loading - I am a big guy and cocking the Beeman P17 is not impossible by any means, but it takes some work. The problem isn't the force of the cocking but the scope rail. It is very sharp and uncomfortable, and the sight is even more so if you aren't careful. Loading a pellet is also sometimes a pain in the arse with the Beeman P17 as I found myself fumbling more often than I would like since the clearance is very tight for loading. Several times after I fumbled a load I would think "Ugh, now I have to cock this beast." Well, folks, this is where the Browning shines on both accounts. It is SOOOOO easy to cock especially compared to the P17. Not only that but, being break barrel, it is very easy to load which can be expedited if you own a pellet pen. The Beeman has no prayer of loading via pellet pen. Not even close. Browning wins this category by a landslide. Also, the Browning cocks by grabbing the barrel, a nice smooth, round spot to grab which makes the cocking even better.

Grips - I like both grips a lot. Browning has a bit of texture which may be nice for some. I like it but also like the Beeman grip, so this is a draw on this category for me.

Safety - Both automatically engage the safety when cocked which I like. What's not to like?

Conclusion - Is the Browning good. You bet. Maybe even great for what it is which is a plinker that requires no CO2 and only needs a single pump to operate. It's solidly built and more thoughtfully built than the Beeman P17. It is not as powerful but take the cocking into account and the possibility to use a pellet pen, and you have far far far less downtime when shooting which equals more fun. In conclusion, I wouldn't say the Browning is necessarily better than the P17 in theory, but in practice, it is better. Focus on cocking and loading more with the P17. Focus on shooting more with the Browning Buck Mark URX. I won't come out and say it's better but I enjoy it more and, isn't that better? Thanks and good luck.

From a distance of approximately 11 ft. (I have a small basement), I hit the bullseye 4 times in a row out of 4 attempts. The accuracy and repeatability is remarkable for such a low-priced gun.
It is also easy to cock, though the front sight can start to hurt your hand after a while, since it is right where you want to put your hand for the best leverage.
Extremely easy to load, and the automatic safety is a welcome feature.

I've been shooting this indoors at about 15 ft and find it very accurate if you control your trigger squeeze and location of trigger to finger location. The trigger design is a bit funny feeling to me. It's not really a bad thing but too much or too little finger and I hit a little left or right as expected but the trigger feel makes it a little harder for me to judge. Overall I love the gun and it's a nice velocity for my shooting in my living room watching TV. I'm sure it will help improve my trigger squeeze and amount of finger to use. Get you one!
