Title: Porting underside of .22 pistol to increase muzzle rise
Post by: tigerclaw on June 16, 2008, 12:03:58 PM
Hey Guys,

I posted this on Sigforum, and wasn't getting much of a response, so I thought I would try it here...

I was talking guns with a friend of mine, and the discussion turned to some of the local matches the gunshop he used to work at (in Canada) used to sponsor/host.

He mentioned that one day, one of their regular guys came in with a .22 pistol and wanted the underside of the barrel ported so that it would increase muzzle rise. He said his reasoning was so that it would duplicate the amount of rise he gets with his .45 that he shoots during competition.

My friend went ahead and did it, and the owner of the gun was very happy with the results. Shortly after that, all of the local guys came in to have the same thing done.

So my question is: Has anybody else here every heard of this, or done it?? It seems reasonable to me at first glance, but I'm forever a skeptic until I've done it myself....

Sounds kinda like a silly waste of money to me.

I think that guy is kinda missing the forest for the trees.... The great advantage about practicing with a .22 is the exponentially greater amount of trigger time that you can log with it. That in and of itself is going to make you a much better shooter without even having to worry about all the other little details.

I personally wouldn't mess with it.

Kinda like putting glass packs on your scooter, huh?

I like the idea.  I shoot a 1911 in .22lr for more trigger time.  However, it is hard to duplicate the muzzle rise when coming back on target with the .22.  While you are never going to duplicate the recoil, this sounds like would help recreate the "work" involved in a follow up shot.

Now the big question ... will my gunsmith have me committed when I show up and say "port this on the bottom?" :-\

I was actually thinking about it also, but having the porting tapped so that I could insert set-screws in the ports.  This would allow me to fine tune things depending on whether I wanted the rise to duplicate a .45ACP or a 9mm.

Nope, I doubt you could get the same rise out of a .22 as a .45 no matter how you ported it. And what .45 did he have.? My 1911 isnt bad in that dept. A Glock is worse. I call BS on this. Sorry but not believing this .

I dont think the point was to "duplicate" the muzzle rise, just increase it from what you normaly get from a .22.
Sounds like it would work to help you with getting back on target, but a lot of expense to practice ONE  detail of the shot.

It may duplicate the muzzle rise, but will never duplicate the recoil.

Yep, as the story was related to me, increasing the muzzle rise was the only intent.

The reason we have truly accurate long range rifles (and pistols) is at least partly because way back in the good ole days alot of reloaders and benchrest shooters tried many screwy things-some of which actually worked out.

If this guy has the cash and he is not engaged in something dangerously stupid let him go.  He may come up with some all of us want.

Best regards,

intresting Idea, not sure how much muzzle rise you would get.

I'm undecided that it will help or not , my theory is recoil generates muzzle rise, he may reproduce more muzzle rise but he cannot reproduces the recoil that causes the muzzle rise Control the recoil control the muzzle. But if you have a device the controls the muzzle you can get back on target. Just put  a devise on the .45 ::) Or maybe your shooting in a stock class only and are not allowed this type of a modification?
