Excellent product fit and trim is perfect also lowers your reset Time dramatically
Love it no complaints at all looks good and really helps
Great product love it will definitely purchase more
I'll be honest, I got this barrel because it looks cool poking out the bottom of my Total Eclipse OWB from Blade-Tech. After putting 500 rounds through it, I'll say this thing is worth more than I paid. The ports actually mitigate the recoil nicely. I was shooting 124gr FMJ 9MM Luger from my newly built P80, and 95gr Cast .380Auto in my son's Walther PK380 and recoil was similar. It would probably be non-existent if I took some more weight off the slide, but looking good is 1/2 the battle.
For the Handloader

If you drop one of these Storm Lake barrels into your once reliable Glock 20 and should suddenly a feed issue arise, it's not the barrel. It's the underpowered factory ammunition you are feeding it. Frustrating yeah?
10mm is elite. The best caliber ever created for a semiautomatic service pistol. The Chuck Norris, if you will, of pistol rounds. 10mm Auto is excessive. 15rds of 10mm is overly excessive.
Before you sport this barrel at the range perhaps it's better to take time to first master the fireball coming out the factory barrel using factory loads. Once you are at that level of proficiency you'll appreciate the advantage this barrel offers. The type of ammunition the Storm Lake, 2-port Glock 20 barrel requires to function, requires you to supply elite levels of cartridge loads. You can't feed this barrel anything other than high octane. Experiment with recoil springs, lube the heck out of it, use only round nose but the reality is this barrel is for the elite of the elite.
REDUCED RECOIL +P (GLOCK 30)
by Dwayne Edwards
Just took out my Glock 30 to the range with the 23 lb. tungsten guide rod and Double Diamond ported Barrel. I shot about 20 rounds of Hornady critical duty 220 gr. +P and the firearm functioned flawlessly. I needed something to absorb some of that recoil along with the Tungsten guide rod to handle some of the hotter +P round for in the wood protection here in Alaska as a backup when hunting or hiking.. It was notable loader due to the porting but nothing a headset doesn't correct. The feeding wasn't a issue at all even with lead rounds. I am pleased with this product and with the Glock 21 magazine installed you cant beat 13+1.
Ordered the black barrel for a g23 and the ports made a real difference on managing the thing, .40 can be a bit of a snappy round and this barrel sure helped there and gave a pretty good accuracy boost with that. Only reason this doesn't get five stars is the black quickly rubbed off on a few points. Not a real problem but maybe the gold or Stainless would hold better with wear.

Stuck one of thes bad boys in my 26 for shits n giggles had to order the glock 19 barrel fit and fired perfectly.
Great for the Rock Island STK100
Wanted to try a Compensated Barrel and this was perfect. I put this in my new Rock Island STK100 G17 clone. I did have to file and polish to make it fit, not much and it was easy. Use a caliber and your old barrel to guide you. I have shot 50 rounds Federal 115 FMJ and it performed perfect with no failures. Very nice product.
