Swany : re the M22 -
No problems with it - I usually shoot 22 Thunderbolt's through that gun - it will take cci mini mags of course
It will not properly eject/feed the Remington bulk 525 pack.
My Tanfoglio is the same way.
When I bought it I got it from Bradis for 285.00 with 2 magazines. I really need to stop in and see if they have magazines - I think they were 35.00 and I'd like to have a couple more. It's a fun gun to shoot
