Thanks for the reply. I've been eying the Hogue wrap around grips for my 220.
I really like the .22 conversion. It switches over is a matter of seconds. My daughter loved shooting it. Easy to handle. Also makes it easy to transition to the .45, although I think a 226 in 9mm might be a better transition for first time shooters. The only problem I've had with the conversion has been the mag. It's made of polymer and doesn't fit right (too loose I think). Creates a feeding problem when the mag is loaded to the max capacity of 10 rounds. 7 rounds or less works fine. Others on the Sig Forum have had the same problem with the mags. They called Sig and got new mags. Problem solved. The conversion also doesn't like all ammo. But the more I shoot it the more it likes. Right now I'm shooting mostly Winchester and Remington plated bulk, and Mini Mags. I'm sticking to the plated stuff since it's much easer to clean afterwards. Blazers tended to lead foul at the muzzle.
Oh, one last thing. The slide doesn't lock back on the last shot, so you need to count rounds (to prevent dry firing) or get a $25 after market part (modified follower) for the mag. That's still on my to-do list.
Hope this helps.
