Just wanted to put in a quick post. I took my factory spring out (Part #51 that goes over the barrel) and replaced it with a spring similar I found at a hardware store, but it was a little too short. So, I stretched the "new" spring a bit and tried it out. 10 rounds of cheap Federal bulk pack bang!, bang!, bang!,... etc. All 10 fired, no fail to eject or feed. NOW I need to buy a spare Bersa Thunder 22 spring from Bersa and take the temper out of the last 2 coils and try it again. It shows promise. Since this was only a test, I must continue with improvements, but when I tried with something other than CCI Mini Mags, like the Federal plinking stuff, it was encouraging.

What does this mean? It means stick with your original spring and shoot hi-velocity ammo, like CCI or the faster Winchester out of it and it should be reliable if you do decide to have it as a backup weapon at home or in the car, etc. Switch the spring to a weaker spring and you "should" be able to shoot with the less expensive plinking ammo for plinking and range fun. I'll let you know how it all turns out.

I took my new Thunder 22 apart and polished the hammer where it meets the slide and made sure that there were areas inside the slide that meet the hammer that also were polished down. Cleaned it all up and even re-worked the safety so that the safety engages firm, positive, but doesn't feel like you are going to take off skin off the side of your thumb to disengage the safety. Nice shooter too!! I should post pics of targets shot with it. Impressive.

Ordered a spare spring from Bersa online today. Will have to give more info when the spring arrives and I have a chance to modify it some and test it. I'll have to test the Thunder 22 with some Remington "Thunderbolt" 22 LR ammo I have.

UPDATE: I shot a target tonight after I got home. Bitter cold out too! 10 rounds of Remington Thunderbolt ammo recently purchased. Used that "stretched" spring and shot at the target at about 15 feet. ALL 10 rounds fired fine, no fail to feed, no fail to eject or any malfunctions at all. Slide stayed open after last round. I was impressed with the group from what I had with the CCI ammo shot earlier. The CCI still did very well for a short barreled, basic "self defense" type weapon. However this target was quite a surprise so I am posting a few pics of it.

I didn't know about Targetz.com. Thanks for the heads up.
Yep, when I want to shoot at targets I print them on my laser printer. This is just one of many optional targets to download in PDF format. Another PDF I downloaded a few years back is a normal bullseye and at the bottom it says http://glockfaq.com however that link does NOT work right to show targets and may now be a "transitional" website, meaning you get something to read there but mostly links and ads for other links. Kind of a parking page out on the world wide web.

Got notice on Friday that the parts I ordered from Bersa were shipped, so should be soon that I will get the spare spring and magazine safety disconnecter (part 42). The later is just a spare to put in the box to return to factory spec. I used my Dremmel and took off the top L hook that pulls the Drawbar/Disconnector (part 28) down when the magazine is removed. With the magazine removed you cannot fire the pistol. I prefer the military version of a pistol that will fire even if the magazine is disconnected for any reason. Sometimes if the magazine does not latch properly and you go to shoot it and it has moved just a few mm down, it pulls the Drawbar down and won't let you fire any rounds. It's a simple fix to make it so that it works (shoots) with the magazine out. Merely take out the magazine safety bar, grind off the hook at the top so that is is flush, polish it back up a bit to make sure no burrs, and replace back in where it was before. Now it will fire with no magazine. Want it original again? Spare part on order is only $2.50 and just put it back in and et voilà, just like factory and the pistol will not fire with the magazine removed....again. I should write up an article for here with pictures showing how it's done sometime if anyone thinks it is noteworthy.
