Trigger Pull: The trigger pull on the MP-655K is in the medium range with the single action being a bit lighter due to less cocking effort required. There is some force required to rotate the rotary magazines when shooting both pellets and BB's. It's important to make sure you use pellets that fit the rotary magazine correctly or they may move around and cause the magazine to bind up requiring additional trigger force.
Accuracy: I found the Baikal MP-655K to be a good shooter, this airgun took me some time to get used to however, so make sure to give it some time and also make sure to try an assortment of pellets as they do effect the trigger pull and the trigger pull ultimately effects accuracy. I did get about a 2 inch 8 shot grouping from an unrested 20 foot out position but I know this gun is capable of much better results. BBs also did fairly well in my test results. My Chronograph testing also confirmed that you can expect to get feet per second rating in-between 300 and 360 fps when using both pellets and BBs.
Build Quality: Excellent, like just about all the Baikal products, these guns are built to very high standards. The designs are sometimes unusual but you can count on the quality to be top notch and in most cases there is little to no difference between the materials used in Baikal's real guns and their air guns.
Realism: The Baikal IZH MP-655K is closely based on the real steel Baikal Viking 9mm semi auto pistol, or (Yarygin pistol) the latest Russian standard military-issue side arm. As far is looking and feeling like a real gun, it sure plays the part. Both the air gun version and 9mm version have steel slides and polymer frames.
Comments: The Baikal MP-655K Pellet and BB Air pistol is another excellent product from Baikal, it is an extremely unique air gun in that it shoots both pellets with an 8 shot rotary magazine but can also shoot up to 100 BBs with its integrated 100 round BB hopper and special adapted magnetized rotary BB magazine! The quality of this gun is outstanding and there are tons of great features like the rifled barrel, fully adjustable sights, single and double action trigger, moving slide with slide catch, weapons grade materials and of course the ability to shoot both pellets and BBs. You are going to need to take some extra time to fully understand how to best use this air gun but the extra effort is well worth it in the end!
