Hey all,

I recently bought a PC Carbine. I only have the one Ruger magazine for now, and it's only 10-round due to state limitations. I watched instructions on how to install the Glock mag adapter and it seems easy enough, but I'm wondering if it's necessary. I definitely want to buy a couple extra magazines to avoid wasting time at the range, but debating if I should stick with Ruger or commit to Glock.

Any advantages to Glock mags other than availability?

Thx
 
I kept mine as is, using Ruger magazines. I have two Security 9's which take the same mag, and don't have any Glocks.
As far as the carbine itself, mine has been accurate and reliable with many different 9mm factory loads. I've shot 115, 124, and 147 grain bullets, and the 147 grain loads shoot best in it.
 
FWIW, I traded into a Ruger 9mm carbine back during the China virus, and went with Glock mags because they seemed more available at affordable prices, at that time. Since then, I've picked up a Ruger Security 9 compact, and I've also
had good luck finding Ruger factory 9mm mags cheaper than Glock mags on GunBroker. I've actually been thinking wbout switching back to the SR carbine magwell, and giving my Glock mags to my nephew. Looking back, I should have just stuck with Ruger mags!

As always IMHO, YMMV, FWIW, etc., etc.

I went through ~100 rounds today with the Glock mags using S&B and Federal 115-grain ammo; no issues with either, and it was a blast. Once I got the optic (Romeo5) dialed in, my groupings were tight at 10 yards. Not so much at 25 yards, but not horrible.
 
If this thing didn't use glock mags, they probably still would not be making it. But what ever you have the most mags or mags you want to use.

In a review I did read on person who had an issue with ruger ,mags, but that doesn't really mean anything. Use the mag you want, and test it out.
 
I ran across a video on the interwebs that went into detail about potential issues with using glock magazines in the PCC's. Im not saying this is a thing but... the video was convincing enough that I decided to stick with the Ruger steel magazines so I bought a bunch of those. If push comes to shove, ive got ALOT of glock mags so I may use them down the road but for now im using the metal ruger Security 9 mags and havent any issues at all.

Heres the vid if anyone wants to check it out and comment:
