The Disconnecting Magazine Fix (& Tweak!)
Some of P22-ers have had the magazine come out of the gun while firing. Confusing and embarrassing at first (especially at the range), this problem may be one of the easier ones to fix, or modify your gun for the tweak also included. The primary cause is due to the size of the gun. To replicate the problem take your safe and unloaded P22, put in a magazine, and engage the safety. Now, pull the trigger all the way to the rear, and hold it there. If you are at your desk, even better (and not doing your normal/proper hold). Look where your index finger is (the pad). It is low on the trigger, a perilously close to the magazine release. If you wiggle your finger a little, and try to engage the mag release, you can. Now imagine a nice Hyper Velocity round going off at the same time, you can see why some people will in fact drop their magazine out. The fix? Just hold up higher on the trigger, and be conscious of a good hold. You want the web of your dominant hand up into the top of the grip pressing at a 45 degree angle into the grip and slide. This helps eliminate recoil (more useful for a 9mm or .45 than a .22, but still), giving better control, and better trigger placement, giving a more reliable/repeatable pull and keeping you further from the magazine release. Keep in mind a change of form when rapid firing. Keep good form and build up speed and you should be able to not release the magazine....Excerps from rimfire.com forum
