I just turned 21 a few days ago and bought my very first gun. The Springfield XD 45 ACP 4 inch service model with thumb safety. Honestly the best birthday ever. I always thought that I would never be able to buy a gun because of my past but 22 hours later after filling out the 4473 form I got approved. I have shot other guns before but to be honest I am not experienced and don't know a whole bunch about them. This is the first time I shot a 45. The day I applied for the gun I shot the glock 41 the 1911 rock island and of coarse the XD 45. The glock was uncomfortable and shot weird for me. The 1911 was comfortable and shot very well with tiny bit better grouping. The XD was my favorite cause it was very comfortable and good grouping plus all the amazing features on it. Very good price brand new. 519 dollars. So happy with my purchase.
