Called around and finally found a Gen 4 G21! I rushed down to the shop and picked it up after work yesterday. I cant wait to shoot it! It feels pretty good in my hand. I like the Gen 4 grip! I did notice a little slack in the slide to frame fit at the rear. It rattles a little if I shake it side to side. Anyone else notice this? Sorry no pics, not sure where to host them, besides its just a plain jane G21 Gen 4 we've all seen them before.
