What's the Easiest Handgun Cal. to Suppress?
Smaller bores supress better, fact. Smaller cartridges supress better(less gas volume for supressor to have to work with). 9mm subsonic is about as quiet as you can get in a current service caliber auto loader. SDTA makes a tube(B tube) that threads directly onto the Liberty or Gemtech LID(Nielsen device). Loading 147grn subs is easy, faster powders are quieter.
The only problem with the SDTA Titanium B tube is it is somewhat small compared to commercial cans, volume wise. And, it is quite heavy as the cylinder walls are about .08. The B tube, turned down to .06 walls shaves almost 2oz off the weight. And I know because I built one just in last month or so. It is quiet enough to shoot standard 115grn supers without ringing the ears, with subsonics, you can here bullet impact and brass hitting the ground. But it isn't near as quiet as 300blk on single shot rifle or 22lr cans I've built.
