I got a Chiappa/Puma 1911-22 a while back ($250), so I thought I would report on it. I finally got a chance to do some mods on mine, that I learned about on other forums:
- buff and drill trigger
- buff barrel "hood"
- add hogue wrap-arounds
- add adjustable rear sight (had one laying around), so no filing on the front sight.
- trigger job. Now trigger breaks nicely at 3.5 lbs. It was about 7-8lbs
- adjust extractor to grip better. Still needs more work...some occasional FTE issues.
It shoots really well and has a nice, tight grouping. I would like to get the extraction to be more bulletproof. I learned a lot by doing a complete tear-down while working on the trigger. Nothing really difficult and now I understand the internals a whole lot better. Now I just need to get some more mags. I may also refinish it, since the paint finish is pretty cheap.

I have completed some more mods to the Puma that really helped fix all the issues that I have. I worked a bit more on the extractor by giving the edge a shape that better resembles the sharp-edge extractors that Volquartsen sells for the 10/22 and 597. This shape helped the extractor slide into place better and grab more of the rim. Now, when I cycle the slide slowly by hand, the shell actually stays in place, pinned against the bolt face until it hits the ejector. Before, there was so much space that the shell would just fall out. This change makes extraction much more reliable than before.

Then, I went after an annoyance that I have. When one attempts to disassemble this pistol and removes the grip panel (left side), the plunger tube falls out of place quite easily, the plunger and spring will shoot out, and the slide safety bar and spring will fall out. So, parts fly all over the place if I you are not very careful. Also, this requires that the grip panels fit well enough to pin the tube in place, making it harder to use some replacement grips. So, I used JB Weld (2-part metal epoxy) and I glued the plunger tube in place and clamped it overnight. If you do this, REMEMBER to put the slide safety bar in place underneath first or you are really in a pickle. It worked quite well for me, however, and the plunger tube now acts like a proper one that has been staked to the frame. There is really no need to ever remove it or the safety bar, so you are free to remove and replace the grips with far more ease than before. I am very happy with the performance of this pistol now and I really enjoy shooting it. I have about 500 rounds thru it so far, The trigger is sweet.

I also just got a GSG 1911 ($320), so I got to give it a good comparison test.
The GSG 1911 is very nice. It shoots really well and feels more like a real 1911. It is just as accurate as the Puma and requires less tinkering to get dependable ejection. It has a lot of parts that are compatible with real 1911s and it disassembles in a more standard manner. However, during take-down, an extra pin and a hex bolt must be removed as well as the slide release. The only thing I really didn't like was the heavy trigger pull (7lbs), and the magazine disconnect that prevents it from firing with the mag out. I removed the spring and bar that comprises the mag disconnect, and it dropped the trigger pull to 4lbs. So, now it behaves more predictably like a 1911 and the trigger feels better. Overall, I think I prefer the GSG and would select it, if I had to choose only one. I still need to put a lot more rounds thru both to get a feeling for durability. I have about 300 rounds thru it so far and it behaves admirably. It holsters perfectly in my 1911 leather and is great to practice with. It also looks nice.
