Both Guns are good and reliable.I discovered a gun store/range yesterday called "the 911store" in Hollywood, FL. Really friendly, knowledgeable staff. I went in kinda pricing a xd9 subcompact, and they let me fire a Glock 19. The glock is really nice. I would like to know if either gun has an advantage over the other. I have fired both, and they both feel good.
SA pros: Lifetime Warranty on the SA XD, and added grip safety. IMO, Better grip then the Glock
Cons: I cant think of any
Glock pros: aftermarket parts are easier to find, everyone has one
Cons - I heard that Glock does not recommend shooting lead bullets through them
kdflyer - I bought my XD9 service for 489.00 at Gun-Tech in Ft Lauderdale.
