The intro to this post is in the post – “Suppressor Do’s and Don’ts” , where I describe buying a Glock 23 in .40 S&W with a threaded barrel to use in testing a Ti-Rant M45 suppressor meant for the .45 auto cartridge. My enthusiasm for this segment of suppressor testing began to wane a bit, when I discovered that Glock uses metric thread pitches on their factory threaded barrels. After a LOT of discussion with various folks in the industry, I found that the Ti-Rant suppressor would fit the Glock threads – and those on Sigs and HK’s – but only if the standard booster piston were replaced with one threaded M14.5 x 1 LH. My “normal” supplier was out of these pistons, so I bought one from Midway USA, and had it overnighted to me. Changing the pistons out was not especially difficult once I discovered how to do it, and the new piston fit in just right – AND it now screws on to the Glock threaded barrel!
By the way, for other common calibers on Glock factory threaded barrels, the thread pitch is:
9 mm – 13.5 x 1 LH
.45 – 16 x 1 LH
When I headed for my woods property “range” to test fire this combo, I had a box of Winchester SXZ “Personal Protection ammo, loaded with 180 gr Jacketed Hollow Point bullets. Although I have seen lighter bullets advertised as being loaded to a muzzle velocity of 2000 fps in .40 S&W, most of the 180 gr loads are actually sub sonic – mostly less than 900 fps. I have suppressor sights for this pistol, just haven’t mounted them yet, so I was shooting for sound, mostly – although just “aiming” down the suppressor produced accuracy at 15 yards that would be suitable for home defense.
Recoil with this pistol/ammo combo is a little snappy, but not much. It was less with the can on, than without, and I would think that the extra weight of the suppressor helped with that some – except it weighs hardly anything! Of course, another advantage to suppressors is that they DO reduce recoil. Even though this one is much larger than the .22 LR can I’ve also been testing, it is lighter – and on the tupper ware Glock is a lighter setup than my Ruger .22 LR + suppressor.
Although it might be challenging to find a good holster for this rig, I think it would make a great woods-walking set-up, quiet enough to use for stealthy snake protection or pest control, yet having enough power to take down a hog – or deer – at close range, with a well placed shot. Personally, I have been lucky and never had to shoot a deer more than once, but many years ago a good friend got pretty beat up trying to cut a wounded buck’s throat with a pocket knife, rather than shoot it again. Having this suppressed .40 S&W Glock in the stand would be a much easier and humane way to “finish off” game – and in the long run, probably quieter than a knife!
Of course, as a home defense gun, the suppressed semi-auto .40 – especially with a high cap magazine, and Glock offers a factory mag with a capacity of 22 rounds for the G23 – would offer lots of firepower, and a lot less hearing damage, were it’s “help” ever needed!
In the future, I may very well obtain a 9 mm barrel for this Glock, to be able to use it as a “test” platform for that caliber, suppressed, also.
