to compliment and/or possibly replace my xd. When I bought the xd, I got a free Springfield xml light - (this one http://www.gunbroker.com/Auction/ViewItem.asp?Item=83694392 ) it’s a pretty cool little light. Would it fit on the Glock? The Springfield uses a Picatinny rail, the Glock does as well, correct? I can’t seem to confirm this right now..I’m probably tarded. Also, how many of you guys use the compensated Glocks (17C, 19C, 21C etc) or compensated pistols in general?? Also, when buying new they come with 2 magazines, correct?
