Well, here is the promised mini-range report & Glock 36 comparison. Range Report First off, here are the targets. I fired 50 trouble free rounds, all I had time for I am afraid during lunch.* They were 230 gr Remington range ammo, so nothing special. This was just kind of an initial function test and a bit of trigger familiarization. * These are the two best targets. Not too bad for the first time firing the gun. It took some time but after a lot of range trips I can shoot the G36 very well. I must say I did not shoot it this well after only 50 rounds though. I am probably just more used to this type of pistol now. Glock 36 Comparison You can see from this side comparison that the G36 is larger. It is certainly longer and taller. This view from the rear shows the more slender nature of the XDs. Yes, My G36 has factory night sights. This slide-top view shows that the slide seems a bit thinner. Here are the magazines. The side view seems pretty close in size, especially if the G36 had a flush fitting magazine. However this view from the fronts of the magazines REALLY shows off the huge difference in magazines. I have always been critical of the thickness of the G36 magazine. I know Glock likes plastic, but look at how much thinner a metal magazine can be. Granted, the G36 magazine has several metal inserts, but it could have been thinner if made of metal. I guess this shows the progress of a few years of magazine design. Initial Impressions So far I really like the XDs. I bought it because of the added safety of having a grip safety and the smaller size. It has functioned perfectly, but with only 50 rounds it is too early to tell. My G36 has been perfect and probably has nearly 1,000 rounds through it, so the standard has been set. I really do like the smaller size, but you do loose 1 round unless you opt for the optional larger magazines. The smaller dimensions make the XDs a lot easier to carry and conceal. It is not a tiny mouse gun though, so do not think you are getting something the size of a Ruger LCP. I think this is about as small as a .45 ACP pistol can get and still retain any durability and usability. Neither the XDs or G36 are range toys. Both are smallish and a bit challenging to shoot. Both seem capable of similar combat accuracy. So, bottom line - has the XDs replaced my G36 for CCW duty? Not yet but it looks very promising.
