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.
