SIG P320 Tsunami

If think a gun is drop safe, try dropping on your bare toes.

Not even Nerf guns are drop safe.

Great range test of my FN 509.  150 rounds flawsley through it.  I have installed blocks inside the 15 round mags to limit them to 11.  Now you may ask yourself, “WHY?  IDPA limits CCP division to 10 rounds in the mag when the start signal sounds. 10 plus the one in the chamber, hence 11.  Helps keep me from putting in too many and getting a penalty.  Also, it compresses the mag spring so on my last round the spring is compressed like there are five more in the mag.  Might, MIGHT, cut down on potential FTF last round. Also, if I were a real gamer I’d make them out of metal to add weight to the gun and to speed up magazine drops.

But let me be clear, FN mags are well designed with clearly visible witness holes for every round.  Unlike Sig which only had holes at 12 & 15.  And unlike Glock which aren’t easy to see which hole is covered.

The Dawson FO sights from my P320 are a perfect fit.  Only problem was I put the short front sight on instead of the tall one.  So the gun shot high.  Have swapped it out so all good now. 

My P320 holsters fit perfectly just by loosening the set screws a turn.

I’m ready to go now.  The Midsize is a perfect compromise between the Comapct and the Full size.  I can use it in  SSP, CCP, and CO divisions of IDPA as well as all pistol divisions of USPSA/Steel except the 1911 one.

Looking at all the recommendations from the forums, I didn’t realize how many  models didn’t make the IDPA requirements.  Wather PDP are too tall, Canik’s are too wide.

Only negative is the cost and availability of mags.  The Compact and Full size are more popular models and hence more availability of parts.  I try to stay OEM with mags, but I’m going to have to give ProMag a try.since they’re half the cost.  I think I can buy the 15 round Compact mag and just remove the sleeve. Worst case is replace the baseplate.  Oh, who do I know can 3D print their own?   Oh, me.

I bought 2 10-round ProMags for my P10-45. They were both such junk I smashed them with a sledgehammer and threw them in the trash where they belonged. Since then I've only bought 2 more ProMags, a 10-round and a 15-round mag for my Ruger LCP, but haven't tried them out yet. If they work, cool. Maybe I'll get a 32-round drum just for S&G. And if they don't work, hammer time! All of my 6 and 7 round mags are genuine Ruger brand. I won't waste my money on ProMag brand in stock sizes. I should take my LCP and all my mags with me when I go up north this weekend.

I'm leary of 3rd party mags, though I do have TandemKross for my 10/22.

BUT at $50/ea for FN mags vs $17.99 for ProMag, I'm going to risk it.

I would definitely risk it.  I've never had an issue with ProMag products.  I've purchased them for CZ's and Rugers.  Maybe even 1911's...old I can't rememememebbbbeerrrr.

You pays yer money and takes your chances. Let us know how the ProMags work out Alf.

I bought 2 other ProMags. They were 20-round .45 ACP mags for my Para-Ordnance pistols. I threw away the weak springs that were in the new mags and replaced them with ISMI Springs Para-Ordnance 170mm Magazine Springs. Manufactured from Chrome Silicon alloy these springs are designed to take less initial “set” to enable a more stable load and increased service life. This 13 coil spring for use in Para magazines up to 170mm length. I also threw away the cheap-looking magazine followers and baseplates, and replaced them with genuine Para-Ordnance parts. After replacing everything except the magazine tubes, they work okay in my full-size pistol, with most ammo that works in my other mags, but not as well, and not will all the same ammo. I was also testing out a 20-pound recoil spring at the time, and it may have worked better if I switched back to an 18.5 pound spring. I haven't tried them in the other 2 pistols yet.

RE springs.  I plug competition mags to limit their capacity.  In the case of IDPA CCP division 11 rounds. The rules limit you to 10 rounds at the start signal, plus one in the chamber.  The plug adds weight to the gun and also helps the mag fall out quicker.  And it compresses the spring.  In essence my last shot from  mag, the spring is still compressed like there’s 5 more rounds to go.  Mitigates weak spring problems causing Failure to Feed.

2 of the ProMags showed up Look okay, but am disappointed about several things.  Not show stoppers just medium level nits.

First, no witness holes.  Nada.  It would be nice to at least have one at 10.  Am thinking about drilling my own.

Second, neither the floor plate, nor the base plate are compatible with the FN magazines.  Reverse that, none of the FN floor plates, base plates or plugs fit the ProMag magazine.   If you wanted to use some 3rd party base plates designed for FN you're out of luck.

So I've retailored/reprinted my plugs so they fit the PM magazine.  I ended up with them limiting the mags to exactly 10 rounds.  I'll have the 2 FN mags that will hold 11 so I'll use those as my first mag on each stage.

Next week I'll spend some more range time.  Probably do a bunch of 5x5 drills (stage 3 of the IDPA classifier) and see how they hold up.   When I get some additional mags I may do a 1x1x1x1x1x1x1x1 drill.  Good practice for changing mags and subjects the mags to repetitions of last-round-hold-open-reload cycle.

I may hold off on drilling a witness hole until after I shoot an IDPA match with this gun in 2 weeks.  It's a bunch of work setting up a jig and drilling the holes and cleaning the burrs.  CCP isn't my primary division so might be a year before I use this rig again.  Not a great payback.

My 10 and 15 round ProMags for the LCP are loaded in the car, ready to go when I get my stuff together. I was supposed to leave Saturday, then Sunday to avoid the insane Saturday traffic, but I felt sick and slept all day. Michigan Department of Transportation (MDOT) oversees and is responsible for nearly 10,000 miles of state highways, which carry more than 50% of all traffic and approximately 70% of commercial traffic in Michigan. The state removed lane restrictions for 100 of 164 projects starting at 3 p.m. Friday, Aug. 29 until Tuesday morning, Sept. 2. But Labor Day weekend is still among the busiest travel times of the year. Usually I-75 is bumper to bumper for 100 miles with idiots cutting in and out of multiple lanes of traffic at high speed without signalling. No matter what lane you're in or what speed you go, it's bad, and I end up white-knuckling it so bad my hands hurt by the time I get where I'm going. So I thought Sunday sounded better. Now that my friend is retired maybe we'll go Wednesday or Thursday before Labor Day and avoid the holiday rush.
