With ammo scarce and over priced. I'm looking for a way to practice trigger discipline and quick shots. I'm comparing a few products that might come in handy for training, should that stash of range ammo need to be locked away and saved. I'm in the mood for an impulse buy but first, I'd like to hear what you guys like best and why. Here's the lineup... Laserlyte Laser catridges: Small laser pointer-like devices that fit into your gun's chamber; uses your gun's firing pin to trigger a targeting laser which scores against a 'receiver' target. - Pros: Decent reviews. Cartridges come in many calibers; including rifle calibers. Allows you to train with your real gun. - Cons: Expensive; $80 to start for only one cartridge. May wear out due to repeated firing pin strikes. Requires racking the slide after every shot. No recoil. Laserlyte Trigger Tyme: A mock pistol simulating the weight and feel of a real handgun. - Pros: Only $40-$50 It matches the weight and dimensions of a G23/G19. Trigger has weight to it; simulating realistic trigger put and semi auto operation. Cannot fire live ammo. - Cons: Will not match the exact feel of your gun. No recoil. Requires separate laser barrel insert. I haven't seen any posted reviews. Cannot fire live ammo... Numerous barrel-mounted laser devices: - Pros: Doesn't take the direct impact of the firing pin; instead uses the sound/vibration of the firing pin to trigger the laser. - Cons: Expensive; $110 to start for only one device. Requires racking the slide after every shot when using a real gun. No recoil. Reviews aren't all that good. May interfere with holstering/drawing What do you think?
