jrswanson1 Posted January 22, 2016 Share Posted January 22, 2016 I have an older, made in Canada P16-40 Limited. When I purchased said pistol five years ago, it came with three OEM mags. I picked up four Mecgar mags, which hold 16 rounds. Since I started shooting USPSA Limited last year, I decided to pick up three new Mecgar mags. The newer Mecgar mags only hold 15 rounds and have flat, steel bases. Who makes extended bases for these mags? I haven't handled any of the Remington P16-40s, so I don't know if they went with skinnier magazines, hence the question. Thanks. Link to comment Share on other sites More sharing options...

jrswanson1 Posted January 22, 2016 Author Share Posted January 22, 2016 (edited) Thanks, Kenny, that's the exact info I need. BTW, will I need new followers or can I stay with the stock ones? Edited January 22, 2016 by jrswanson1 Link to comment Share on other sites More sharing options...
Trail3 Posted January 22, 2016 Share Posted January 22, 2016 MBX are pricey but they work. Love mine for my 18-9 & 16-40. Mecgar's I bought were the 9mm/38super and did not work when loaded to 15. Tried putting spacers in them and still did not work reliable. In the range bag for practice. Link to comment Share on other sites More sharing options...
fishpinoy27 Posted January 22, 2016 Share Posted January 22, 2016 Mecgars are junk. Try to find Canadian mags. Or go with MBX or sps Link to comment Share on other sites More sharing options...
Gary1911A1 Posted January 22, 2016 Share Posted January 22, 2016 Anybody know if the new shorter Megar .40 Magazines news will work with the Daswsons and the S&A Magwell? Link to comment Share on other sites More sharing options...
ParaGunner Posted January 23, 2016 Share Posted January 23, 2016 I think all mags+extensions will fit with a S&A magwell. Link to comment Share on other sites More sharing options...
jrswanson1 Posted March 7, 2016 Author Share Posted March 7, 2016 I didn't have the scratch for the Dawson's so I picked up two Arredondo +4 extensions from Midway, since I got a birthday discount. I tried them on the newer Mecgar mags. Nope, won't lock in. They work fine with the flat metal base, but no love with the extensions. I switched the extensions to the older Mecgars, and they work. But they only add +2. Cutting off part of the fingers on the plastic plate lets me run 19, but the follower gets stuck. No need to put a new spring in. But that still leaves me with two 15 round mags and no way to make them longer. Looks like I'll have to get those ACT mags if I want something bigger.

dogtired Posted March 8, 2016 Share Posted March 8, 2016 The original Para mags are longer, and will fit an extra round, and fit with a magwell (which were designed with the longer mag). The Dawson website has a good page on the mag differences. Link to comment Share on other sites More sharing options...
jrswanson1 Posted March 9, 2016 Author Share Posted March 9, 2016 Yeah, the newer Mecgars are just a touch too short. Feh. And they decreased the capacity. So if/when I get a magwell, I won't be able to use them at all. At least there's a source for new mags that will work. When I bought these, ParaOrdnance had just been bought out by Remington, and there weren't any new Para branded mags left. Link to comment Share on other sites More sharing options...

dogtired Posted March 17, 2016 Share Posted March 17, 2016 (edited) I just found some new p18 Canadian mags on Gunbroker for $65 each. The 16-40 should be a little cheaper. Edited March 17, 2016 by dogtired Link to comment Share on other sites More sharing options...
jrswanson1 Posted March 17, 2016 Author Share Posted March 17, 2016 Well, this is on hold for now. The extractor on my Para broke, so it's in the shop now. Link to comment Share on other sites More sharing options...

jrswanson1 Posted May 17, 2016 Author Share Posted May 17, 2016 I got two of the Dawson extended base pads in the mail yesterday. After I installed them, I went from 16 to 18 rounds. Unlike the Arredondo extensions, these came with instructions. It seems the older Mecgar mag's followers won't slide past the lip of the magazine into the extension. They recommended (in the instructions) to use a file or sandpaper to round the bottom edge of the follower. I started doing that, then I thought about switching the guts from the 15 round Mecgar mags into the 16 round Mecgar mags to see what happens. The followers don't swap between springs, but it turns out, the newer 15 round mag springs are significantly longer than the 16 round springs. The followers are shorter, too. So swapping out the guts from the newer into the older gets me 20 rounds in the older mags. Putting the older guts into the newer mags still only gives me 15 rounds, but that's a wash. Anyway, I now have two 20 round mags for my Para. I will order two more extensions, and add springs and followers to the order. That will give me four good 20-round mags and two 15 round mags. I'll contact fishpinoy next week about our conversation. Link to comment Share on other sites More sharing options...
