I know I know, but it can be done, IF YOUR CAREFULL. Hey if I ever get any bad side effects I'll let you guys know with a the post, bumbest thing I ever did with a gun. If your scared, even in the slightest don't do it, but if done right it works and it works consistantly (I've chambered at least 100-150 rounds like this with no problems). I'll keep you guys updated and let you know how what the long term results are.
At the very least this may shead some light on why your Bersa reacts this way after extended use, it's just wear on the slide. I like the feature, there is a reason why it's on some other pistols. If anything not having it is just a safty precaution from what I know of it.
I'm not going to argue if you guys don't like it, it's a personal preferance, and I never had the warantee in the first place, I wouldn't have done it if I did. If you did buy your Bersa with a warantee, the warantee is worth way more than any little tweak you could make on your gun.
If you do not know what your rights are, you do not have them.
