Matched Pair Rimfire/Centerfire vs. conversion unit?

Andyd · Feb 1, 2015

I had a KPS conversion unit for my SIG P210-4 and found the feel of the conversion quite different from the standard 9mm set-up. When I had gotten a Hammerli 212 Jägerschaftspistole, the conversion was retired instantly.

While the Hämmerli 212 looks different from the P210-6 and their weight and length is nowhere as close as on a rimfire conversion compared to a standard gun, their shooting characteristics are quite close, closer than the conversion was.

Does anyone else of you guys have "matched pairs" or do you prefer rimfire conversions?

We had a 2nd issue Colt Ace .22LR pistol for years, it worked well with several brands of ammo, with no FTF or cycling. We did strip the pistol down after each range session, including stripping, cleaning & lubing all parts of the slide. I have never heard of an aftermarket .22LR conversion for a 1911A1 (other than Colt's) that worked even fair.

Da gimp,

I have two friends who have Colt Ace conversions that are very troublesome.

Marvel makes several conversion units for the 1911 that are well made and accurate. I have shot one when they just came out and was impressed.

Years back I picked up a Ciener Platinum Cup .22 conversion unit at a really good price. I liked it so much that I built up a frame to permanently mount it on. Its a great shooter, but I tend to like it more on its own merits rather than thinking of it as cheap practice.
Of course there is the ultimate .22 understudy for wheel gunners, the S&W Model 18.

Mine goes to the range quite often and I give it full credit for teaching me to shoot a revolver DA.

I've gotten 2 conversions over the last 5 years........

A Ciener conversion for the Browning HP

And a Beretta unit for the 92.

Neither are "tack drivers"/target pistols....... but both function well and are a hoot at the range...... good cheap practice or trainers.

I've set each up in its own mini range bag; Frame, both uppers, 3 mags in .22 and 4 in 9mm and 50-100 round of .22 and 9mm ammo......kind of grab and go kits!

Years ago I bought a Colt Ace top for my Gold Cup. Lots of fun to shoot, but I got tired of switching back and forth, so built a lower using an AMT frame and a GI parts kit. Now I have a dedicated 22 1911.

I like this better.

Dedicated 22's to back up the big brothers in the form of:

semi auto pistol - Colt 1911 Conversion Unit
revolver - S&W 18
semi auto rifle - Tactical Solutions AR22
bolt action rifle - Kimber 82G

This seems to work for sensible practice in each format, at least for me.
They are very much fun at the range too!

Let's see: Having two new guns versus one new gun?

Hmmmmmmmm

I have a S&W M14-2 and a K-22 also to serve the same purpose and a couple of Korths. I have shot the Korths almost exclusively in the past three months and transition from one to the other is very easy.

Well understand the reasoning for coverson units, and may in the future get on for AR-15.

To me , there is a further split between "understudies" only in the sense of simply using cheap ammo in somthing that resembles a particular centerfire, and those that are fully useful .22's in their own right.M18 ( and other K frame and J frame .22lr's ( and Single Sixes ) are fine pistols in their own right , even if you don't own the CF analog . My Colt brand .22lr M1911 ( the Umarex one , not the Ace ) also functions as a decent all around .22lr in its own right.

I bought a SIG Mosquito primarily as a cute pink pistol for daughter ( not a universal endorsement for pink pistols , but in this case she has a sense of humor and gets the irony), and secondarily as an understudy for full size SIG. It's one of the lucky ones in that it's reliable , but neither the fit , balance, nor trigger pull has much similarity to CF SIG's .

So , it's a case by case thing , with a preference for complete .22lr guns if they are well actualized.

Biggfoot44,

for an AR I would rather recommend a dedicated upper than a conversion unit that has a .223 barrel and marginal twist rate for a .22 l.r.

On a side note, I differentiate between SIG guns and SIG Sauer guns. As a German born individual I cheerfully admit Swiss superiority in the P210 - line and the high standards that they had adhered to in the past.

A conversion unit would allow swaping between rifle and SBR formats.

this is one of my main collecting interests. I think every center fire pistol should have a rimfire conversion available for it.

For revolvers and rifles I like to have a .22 and a centerfire version. I call them father/son sets. It just plain makes sense to have a rimfire understudy of a primary gun.

Here is my Ruger full lug SP101 .22 and my GP100

Well, some make do with switching top ends...

but not me. Bullseye is the only place this question really applies to me since I don't practice my combat shooting with a 22. While these two guns look very different, the weight and balance of my 45 and my Marvel 22 are almost exactly the same. The tungsten guide rod in the 45 helps achieve this very close match.

My 617 and 627 go pretty well together.

I have a Marvel upper for my 1911's. It sits on a RIA frame and is a hoot to shoot.

When I find my perfect Model 19 I have a Model 18 to be its buddy at the range.

I do have a SA XD9 with a Advantage Arms upper as well as a Argentine upper for my Hi Powers. So it looks like I lean towards the conversion side of the question.

S&W has done this for us. The 14, 16 and 17 are the same gun in .38 Special, .32 Magnum and .22 Long Rifle respectively. The barrel/top rib profiles vary slightly to allow them to weigh the same when loaded.

My Wilson .22 conversion on one of my Ruger SR1911's.

eveled · Aug 30, 2015

Another close to matching set, a Luger and a Ruger. I had a chance to buy a Stoeger Luger .22 for a better match but passed, it seemed to be poorly executed.
