Verified Purchase

Things I liked: Ok, you gotta do some mag swaps during your shooting, right? This is the same that came with the gun, so not much else to really say. It works unless it leaks.

Things I would have changed: I had a CO2 leak on one of my mags after probably 10-15 CO2 cartridges. Better reliability would be nice. Also make the follower lock (and stay locked) BELOW the fill hole for easier loading. I have had trouble with the follower releasing while loading, flinging BBs all over.

What others should know: Pyramyd more than made up for the defective unit by shipping me another one. They are awesome!

Things I liked: Flat bottom, it works . It was a replacement for the silver finish factory mag that leaked from the Get go. I prefer this lighter weight mag to the heavy extended mag

Things I would have changed: Optional Silver finish

Things I liked: Nothing

Things I would have changed: Everything as it does not work well with the Sig P226 X Five Open Combo. It has a flat base and does not have the extending base bumper that comes with the mag supplied with the pistol. Hence, It has to be shoved into the pistol and the follower often sticks and does not keep pushing the bbs up.

What others should know: Look around for the mag that comes with the pistol.

  • Luis from USA asked:

    I get that it workswith the "plain" P226 X-Five, but will this work with the P226 X-Five Open Combo? Concern lies with the Open version's magwell.... as this is a flat base and the magwell seems to add some extra deepness.... Has anyone test it this on the Open Combo version? So upon reading the reviews, seems several people have issues with them on the Open version, a seem to work fix relates removing the extended magwell... thus defeating the purpose.... I'll keep looking..... else I will go with the plain P226....

    • GMS from USA:

      As you may have already guessed, they work with the Open even with the extended magwell. It's just not as smooth inserting the mag. unless you palm the baseplate's lip. I specifically bought 2 of the flat-base mag's when I bought the Open, and removed the magwell. Now I regret it because the extended mag's seem to have disappeared, and now I want them for the Open with the magwell reinstalled, with the flat-bases retasked to the X-Five "silver" with the magwell removed. I also wish there are spare "silver" mag's avail. We may need to wait YEARS before that happens.

  • Michael from Canada asked:

    Does this magazine include at least one new screw that holds the co2 cartridges in place?

    • GMS from USA:

      Yes, plus a hex wrench too.

  • Daniel from USA asked:

    Is the mag metal or plastic?

    • GMS from USA:

      Yikes, plastic mag's for a GBB Pistol?? I've never even heard of one. Even those that try to emulate polymer mag's might only have a plastic shell on the outside but actually covering up a metal body. Now, some NBB pistols have mag's that are either metal or plastic. Umarex's USP is one example.
