My silencer candy! I went with a Glock 19 with a KKM threaded barrel since the 19 barrels also fit my Glock 26. The silencer is an AWC Abraxas Titanium. About 3.5 oz, same weight as my TLR-1. This can is a wet can, just under 1" diameter, and just under 6" long. No boosters or LID's needed and it does function my Glock 26 and 19 w/o any problems. I refill the can every 2 mags, (20 shots). I don't use my Hi Caps with the silencer because I need to tighten it every few rounds, and it gets hot that way too quickly!
It isn't the quietest out there, supposed to be around 28/29 DB reduction rating, but I don't need any boosters, works with either Glock and I can see/use my factory sights with it, no need for taller sights. I use it in my NRA class when shooting at an indoor range or with new shooters at the outdoor range. It is quieter inside than a .22lr pistol unsuppressed indoors. No flash, much less Bang, people shoot it much easier than an unsilenced gun. Makes the transition from a .22lr to a 9mm that much easier, as they can get used to the gun, trigger and sights w/o worrying about the flash and recoil and flinching. I read somewhere that recoil is mostly perceived from the flash and bang, so if you reduce those, people don't flinch or notice the recoil as much. Definitely has worked out that way in classes so far! I picked up a couple 10 rd mags, usually load 3 to 5 in each, so I can tighten the silencer, and they focus on 3 or 5 shot groups instead of worrying about having 15 shots to do, which will wear out new shooters quickly. To refill the can, it comes with a turkey baster looking syringe/tube combo, fill tube with lithium grease, insert the plastic tube with holes into the can, squeeze and rotate. Pretty easy and simple to do!
