General silencer discussion. If you want to talk about a specific silenced rifle or pistol, it is best to do that in the rifle or pistol section for that brand.
I had this Spanish Destroyer that I always thought would make a good suppressor host. So I shipped it off to Mike Klos and let him do his thing to it. He was originally going to turn down the breech end of the barrel to shorten the 9mm Bergmann chamber and ream it for a 9x19, then re-set the sights. But we decided a Green Mountain blank would work just as well, with less work. Add a set of tall sights and you're good to go.
I find the magazines don't always like to feed the shorter 9x19 ammo, unless I download to 3 rounds. Flat-nosed bullets especially don't like to feed (no real surprise there). I've ordered a couple of different types of 9mm 1911 mags that I was going to cut a notch for, as they should feed better.
Ammo used was some 147 gr. JHP handloads using N330, Fiocchi 158 gr. JHP, and 147 gr. Federal AE Flat Nose.
I've got one 1911 mag modded to fit the gun. I had ordered the wrong one initially. It's got a rib along the front of the mag, aligning the rounds at the back of the mag. However, it does have a small ramp built into the front of the mag body to keep the round from nose-diving, which was the problem I was having with the factory mags. I thought about returning it, but a couple of dry runs with the mag held in by hand pressure were encouraging. So I ended up notching it for the Destroyer's mag catch and then ordering a couple of the other style of 9mm mag, which has a spacer along the rear of the mag body.
As it turns out, this style works better than I'd expected. Too well in fact. RN and JHP bullets seem to feed well. Where the flat-nosed rounds were nose-diving before, now they are hitting the built-in ramp in the mag body and shooting straight up over the chamber and often getting trapped vertically between the barrel & bolt.
I'm thinking next time I shoot this gun, I'll have to compare it to a suppressed bolt-action 22LR. For that matter, I've got a .243 threaded for a can. It's kind of interesting when using Trailboss powder, shooting at subsonic velocities.
I had started into my project before Ruger came out with the 77/357. To be honest, if I was to do it again I'd probably go with one of those. You have a few more bullet weight options with .38 Spl. / .357 Mag. And for a muzzle can it's just a matter of threading the barrel - no need to rechamber from 9mm Largo to 9x19.
But if you're doing an integral, that's probably less of a concern.
And anyone can build a suppressed Ruger. The Destroyer is a little more unique.

For the buy it now price I can get a Ruger 77/357. I want a Destroyer though, may just have to build one myself if I can't find one for a reasonable price.
I had a friend of mine who had a Destroyer and he said that a modified P38 magazine would work. I saw the rifle and the magazine's he had modified but never shot it. Just saying.
Neat to have though!
