My new around the house gun
Very nice and tight fit and finish. Combined with the bronze mbus sights and p mags this thing looks real sweet, actually very sweet. Sighted in at 100 foot and this thing will beat out a hole the size of your eye ball socket. Running 200 gr. sub. My Daughter wants a pink one now and my Dad wants a burnt bronze so yes, they are nice and I will be getting more. Yes, buy one or maybe 3, you wont be unhappy.
