Just picked up a used 22/45 on NES classifieds. It's been upgraded with Volquartzen and Majestic arms parts. Very accurate but 21 failure to feeds in 200 rds feeding it CCI standard velocity. Purchased this gun with the intent to join an indoor pistol league. This isn't gonna work. Where should I start? Do these guns like a lot of oil. My SR22 doesn't. It has the factory loaded chamber indicator. I think I read somewhere those cause issues. Any help would be great. Ty.
