[How many rounds in a Glock 33 round mag for AR9?]

Thanks for the help guys.  I think the next time out, I'm going to try 32 in first mag (loaded on open bolt) and 31 for reloads.

 

cheers,

Chuck, the Taylor extensions is one of the reasons that I'm wondering if the "33" is actually intended to be a "31".  Before you added your extension, did you load 31 or 33?

[How many rounds in a Glock 33 round mag for AR9?]

I've been shooting the monthly PCC/Tactical shotgun match at Rio Salado for a few months.  I normally run a HK416 clone in .22LR which runs great, but it fails to knock down a lot of the steel targets which is distracting on the moving targets.  I finally built an AR-9 using all PSA parts, billet lower, hybrid upper, KAK 8oz extended buffer, standard AR15 carbine spring, ALG QMS trigger.  Today I ran it for the first time using Glock 33rnd mags.  I had a couple that were loaded to the last viewport (31rnds) and they seemed to do fine.  For the last stage I shot (Stage 1), I loaded them to 33rnds.  BIG mistake, I was jam-o-matic on each mag change, loading against a closed bolt (no LRBHO) and it usually failed to strip the first round.  How many rounds do you guys normally put in the Glock 33rnd magazines?  If less than 33, do you also download any of the other common sizes (Glock 17, PMAG 21,etc)?

 

cheers,
