The Stribog line of subguns, pistols and pistol caliber carbines are really cool. When the brace fiasco erupted, I sold my 9mm SP9A1 and regretted it. When Grand Power said they were coming out with a 10mm, I was an early buyer. One question popped out though – what was out there to help load the 20 round 10mm magazines? I hate loading magazines with stiff springs as many hands start to cramp so I needed to find a loader.
First off, they are HK UMP pattern magazines
The Stribog 10mm mags are nicely made, beefy as hell and based on HK’s UMP magazines. I like that – I am really tired or proprietary mags where you have one and only one option. Using an existing mags opens up options. Now, are UMP magazines all over the place and cheap? No, they aren’t – especially not 10mm mags. HK doesn’t make 10mm UMP magazines any longer.
Real HK 10mm mags have starting costs around $139 but are 30 rounds so there is a perk for the price. Considering Stribog mags list at $45 and can sometimes be found for $39.99, I’ll stick with Stribog mags.
Stribog 10mm magazines are built like a tank
This is both a pro and a con. The top sports a lot of reinforcements making for a quite a large magazine in terms of circumference. They will not fit inside a Maglula Universal loader – I had hoped they would but it is a no-go.
Playing a hunch
Ok, so I did some searching on .40 caliber and 10mm UMP loaders and then played a hunch. I make magazines for Rock Island Armory’s A2 HC .40 and 10mm pistols. They use a staggered magazine and my source tube for the custom mags I make is actually a Mec-Gar .45 mag. What if a UMP .45 loader would work? I had a pretty good hunch it would so I started researching them.
The UMP .45 is much more common so I had options. The one that caught my eye was from Custom Smith so I ordered it and must say I am impressed.
It is 3D printed and nicey done. Everything seems thick enough to have proper rigidity. I like finger rests on the sides to give your hand something to get hold of. I promptly loaded two mags super easy. You push down, slide the cartridge in part way, lift the loader up, slide the cartidge in the rest of the way and repeat.
Grand Power Stribog’s 10mm model uses magazines based on the HK UMP design. The Grand Power magazines are affordable and relatively easy to find. You may need to dig just a bit as the 10mm Stribog sales are outpacing magazine availability but I am sure the mag availability will catch up.
To load the stiff magazines and save your fingers, get a UMP .45 loader. I went with Custom Smith’s UMP .45 loader and have no hesitation recommending it.
No, I wasn’t paid to write this – I had to buy it because I wanted the 10mm Stribog and manual mag loading kills my hands.
By the way, S&B 180 grain FMJ 10mm is my goto range ammo. It’s affordable and runs great. I use it for breaking in and target practice with all of my 10mms.
