I had one previous. At the time with fullpower loads, a recoil spring upgrade was recommended. I only got rid of it due to cost to shoot. If you reload ymmv. I liked the gun though. One handed shots from an unconventional (knocked down , injured etc.) might be difficult. Imo this is a training issue but again cost to shoot comes into play. All in all excellent 10mm though. Doubletap was the heavy hitter at the time along with ga arms. There might be more fullpower factory loads available now.
