FYI: testing a 10 round PMAG and 5 rnd extension

[Skully]

Just an FYI in case someone was thinking this as well.

I hate the look of 20 or 30 round mags with blocks for only 15 rounds, deceiving in knowing what it really holds and I hate pretending.

I couldn't find a good review of anyone taking a 10 rnd P-mag an adding on a 5 round extension. There is no MAGPUL quality 15 round mags that look like 15 rounders. I am surprised someone hasn't thought of this and marketed to CO or other restricted states. If this would actually work that is.

So I experimented on the cheap, bought a 10 round pmag for $10 and a strike industries 5 round extension (they advertise this increase for typical 30 rnd mags so I figured it would work) for $10. I chuckled thinking the online seller who marked restricted states on the 5 round extension would deny the sale, but I bought the two together so I am thinking they knew I meant the two was going together in first place for the CO legal 15 rnd mag limit and let it go through.

Looks better than the blocked larger mags, and not so silly as the 10 rnd mag in the magwell, but the biggest kicker?


I can only get 14 rounds in the mag. Not sure if other extensions will work, but I am not wasting more $$ to try at this point. I was thinking it has something to do with the follower, but they look the same as the regular mags, then I read somewhere the 10 rd pmags actually use the 20 round spring, so I deducted that the spring compacted is my limitation.

Now I got a good range mag for sighting / plinking and a "not to grab attention from others" mag in public.

At least I am not out too much money, but for the next guy be warned if you are thinking this may work, it doesn't actually get you to the 15 rnd limit, but 14 rnds is better than 10.
