Thank you all for the information on this firearm. I purchased a 10mm version as a woods gun for hiking and camping and had no idea what I had. Knowing that it's a Stock I slide, do you think it can handle Underwood 220 grain hard cast with a 20# recoil spring and a Henning cone fit guide rod? Not looking to shoot a steady diet, just sight it in, put a few hundred rounds of range ammo through it and a box or two of the Underwoods to see if it feeds reliably. New to 10mm, I know commercial ammo is mostly downloaded. Thank you and sorry for the threadjack! Sent from my SM-G970U using Tapatalk
