Sig 226 Lock Time Myth or Reality?

Sebastian the Ibis · Sep 10, 2016

I am in the market for a 9mm Suppressor Host.

The rumor seems to be that a Sig 226 has the longest lock time, as such it makes the quietest host. However, I can't find any substantive articles or discussion on this. Most threads are of the, I have [insert my favorite pistol] and it works great variety.

Does anyone have any articles or experience comparing lock times of 9mm pistols? I would be interested in knowing if this supposed benefit is limited to the Sig 226, or if it also extends to the 2022 & 229.

Similarly, how does a factory threaded CZ compare?

I don't really know what you're looking for, but there is this from the late Stephen A. Camp...

The telltale firing pin "wipe" is present on the primer fired in the SIG-Sauer. This is typical and to be expected. The SIG-Sauer pistols purposely have a bit slower firing pin retraction to help thwart debris from entering the firing pin channel.

I have no idea what lock time would have to do with quiet (are you maybe a victim of auto-correct?). Speaking only for myself, I'm not good enough to notice the lock time on any properly functioning firearm I've ever shot.

One failing the Sig P226 does have is a *long* reset. I've put the short reset trigger kit on mine, which helps a lot.

I'm thinking OP meant lockup time, as in the time it takes for the barrel to unlock from the slide. Lock time generally refers to the time between when the trigger is pulled and the round is fired, which would have no effect on the sound level.

One can increase the lockup time of some pistols to a point by swapping out the recoil spring for a stiffer one. Wolff sells non-captive guide rods and recoil spring calibration packs. The idea is to install the heaviest spring that still cycles reliably with your chosen load.

I sincerely doubt a Sig would remain locked as long as a Beretta Brigadier (or even standard 92). The Brig has a much heavier slide and barrel and longer distance from full battery to unlock than most any other recoil operated pistol. (I've weighed and measured several guns to confirm this).

The best would be a Luger, because it unlocks so late in the firing cycle, but I doubt that's in the running.

I was actually wondering how a Hi-point would compare. A big heavy slide and fixed barrel would seem like a winner in this whole lock/lock up timing. However, I don't think they make a threaded barrel.

A Hi Point has zero "lock time". It is straight blowback.

Correct. Hi Point is one of the few manufacturers still using an old school simplistic blowback design so there isn't a locking action happening there at all. It's a good design IMO because there is so little going on internally and the design has been used by various companies for a very long time.

Yup, that's why it would win the "lock time' race.
