SnapCaps = yes. Barrel exit or noise = no. Though there are a variety of different types of SnapCaps (though I keep using the brand name); search Brownell's or Midway.ianmko wrote:Are dummy rounds the same as those dark red snap caps? Do they exit the barrel, or just make a noise?
Very, very few modern pistols have their firing pins damaged by empty-chamber dry-fire. But using SnapCaps not only gives the firing pin something to cushion its blow, but it allows you to practice a number of functions, from semi-realistic mag changes (reloads) to common stoppage clearance. I have and use SnapCaps in all calibers I own...well, except .32 ACP. Never mind. When practicing dry reloads, I always have a SnapCap in the new magazine. Makes for a more realistic insertion, and helps insure I don't accidentally damage the feed lips.
Glock aficionados won't like me mentioning this, but when it comes to dry-fire practice your XD's fire control mechanism has a benefit over stock Glocks. Once you've reset and activated the trigger, your XD will still allow a pull through its normal range of motion, albeit without the sear resistance and trigger break. With a Glock, once you pull the trigger it's pinned to its rearmost position. The upshot is that you can practice trigger control on an XD without resetting the trigger each time.
But like AndyC noted, be certain the sights on your gun aren't wacky. Most aren't, but I bought a PM9 once where the sights were visibly misaligned just looking at them out of the box. Have a good shooter try the gun or, perhaps easier, shoot it from a bench rest. Doesn't need to be anything fancy, just a secure rest--a sandbag, a rolled-up towel, a backpack--that will help eliminate freehand glitches from your shooting. If you shoot your XD from a solid rest and it still groups low-right, it may well be the gun. This assuming your sight alignment is correct.
You selected a good firearm. A little work, and you'll be very accurate with it.
