I've heard it's feast or famine with the sigs. Some function flawlessly, while others you can't get a mag through. I also think that it depends on the ammo used, Remington is garbage, and federal is King.
Mine runs Remington golden bullet flawlessly with the suppressor on it. It shoots a bit high and the sights that are provided don't give enough adjustment to compensate so I have to adjust to that. Fun pistol, but had a very heavy trigger, I like mine better than the 22/45 I had and the Walther p22.
Without a doubt, the Ruger 22/45 was a better weapon than my mosquito, It just doesn't look / feel like pistols that I am accustomed to shooting. I traded my threaded barrel 22/45 to a forum member.
How about that, I had one listed for about a month, with no bites and had to almost give it away. you are getting more action in one day than I got in a month.They seem like fun pistols , no comparison to a quality conversion kit.
