Please, no comments about how the muzzle flash at night and shooting from retention are liabilities. Or how one should get a smaller caliber if one feels the need to have a ported barrel. We've all heard that a million times before. I'd like to hear from those with actual experience.

Just from a physics standpoint, it'll be the full-size with the biggest recoil that gains the most from being compensated. So, probably the G20.

I had a 19C, and it felt like a .22 mag. Zero muzzle rise. Shot great.
I just recently acquired a brand new Glock 17C, so I can't comment on it yet. The front sight gets dirty after a few boxes of ammo, but I just wipe it off with my finger and it's good to go. Those are the only models I can comment on. I guess my post isn't really helpful, since I have zero experience with the other caliber compensated Glocks. |

The only one I've ever shot is the 23C I own. I love it. Definitely helps out a lot compared to the regular 23. I also will shoot it at night every now and then to put on a show for my friends.

Touche', my bad. Thanks for the responses so far. felrom - You're probably right. But I find it interesting how subjective experience is so different between different shooters when evaluating the 21c and 22c (which have totally different recoil impulses). A_I - No, that is actually helpful. I've heard people claim there was no difference between the 19c and a standard 19. Your experience tells me otherwise. Neon and esstac- I've never noticed any of the C Glocks I've shot being louder. But I've never tried firing them in an indoor range or under a low roof. |

mic,
Two questions: Are you planning on swapping out the stock sightis? Which has better shooting characteristics for you (speed, fast follow-up shots, soft feel, etc), the 17C or the 19C? |

20C.
Add in some tactical-nuke rounds like Underwood's or Doubletap's 135-grain screamers, it makes a huge difference. |

Yeah, I want get a set of night sights installed. For me it seems that the 17C is faster and more accurate due to the weight and longer sight radius. The extra length in the barrel and grip also helped make the 17C more controllable over the 19C...... |

Only have the 17C so I can't compare but surprised how tame it is. You can get lazy and not have the best grip and still be ok. Shooting it in close retention is no fun. That's for sure.

I shot a G23c years ago before I bought my own 23. It was very tame. I had a coworker always threatening to sell me his G17c for months. Any time I had the money with me he would say "well, I have to find a replacement first." Bastard got $250 trade to a Ruger 345.

I owned a G23 C and it shot fine and it did not appear to be any better then the non C models to me. The one thing I noticed is after a few shots the front sight is covered in carbon causing my tritium to be less visible. To the average person it would not make a difference when most of you just shoot during day time at the range. I was shooting for a qualification at night or handgun classes which covered low light to no light shooting firing lots of rounds. I sold the 23C and bought a G19 but if you need a C version to help with the muzzle flip then go for it.

What happens when you fire from retention or while trying to defend from a weapons takeaway attempt? Basically when you have those ports right next to your body are they going to damage flesh?
I have torn range bags by getting my carbines flash hider to close, and I have shredded paper and cardboard targets with the muzzle blast from a pistol. If I have to make a contact shot into someone's body I'm going to be holding the slide closed with my support hand when I fire the weapon. In that situation I really don't want to blow the meat off my fingers... |

Many who are against the Glock "C" models have never even shot one. |

I came into a Gen 2 G17C that was a former duty weapon of one of the LTs at my PD. Roughly 10,000 rds through it and the trigger is amazing. I had one of the Dept. armorers tear it down and it was in great shape. Paid $200 for it. All I did to it was put some Decal Grips and XS Big Dot sights on it. I've run it through several classes--with mostly steel cased ammo--and it is boringly reliable. I did not notice any insane muzzle flash from the porting as myths on the internet suggest. Shooting from contact/retention, however, I do notice the gases from the ports shooting upward towards my face, but it doesn't burn or anything. It's just...noticeable.

I have a Glock 17C, I hated glocks before trying this gun out. I've had a 21, 19, 29. all of the grips felt weird to me, but the 17 fits perfect. I'm a CZ guy but I shoot the 17C so well that I take it out more often than the SP-01 now days.
my most accurate load for the 17C uses Win 231 and it is the more flash producing load ive found, but the flash has never bothered me, especially when it helps me stay on target. |

I'm pretty sure KKM WOULD do them again if there was enough demand for them. I BADLY want both a Glock 26 & Glock 33 Hybrid barrel. The Hybrid I had installed in my Glock 27 made it controllable shooting CorBon .40 135 gr +P loads. Like an idiot I sold the 27. I currently own a Glock 17 and Glock 22 with Hybrid barrels. |

I have two 17C's and used to own a 19C.
I like the 17C's a lot better and feel that the porting actually makes a bigger difference than in the 19C. I bought mine shortly after they were discontinued (I think I bought one in September 2014 and the 2nd in December of the same year), and I paid no premium over a regular 17. I looked at some sold gunbroker listings the other week and they seem to have really shot up in price. |

The ports DO have the potential to do damage. I was shooting qualification with my Glock 22 and the ports were causing pieces of the suspended ceiling to rain down on me after every round. |

I borrowed a 17C and 19C from a buddy and took them to the range along with my familiar 3rd gen G19. To be honest, I didn't notice a big difference between the 3 pistols. The 21C and 22C definitely make a more noticeable difference compared to their non-ported counterparts.
I couldn't determine which gun shot flatter and softer between the 17C and 19C. They were ever so slightly softer shooting than my G19. I brought a shot timer to see how the guns behaved in speed. My fastest shot splits were in the .15-.16 range, which I could accomplish with all three guns. I couldn't shoot any gun faster than the others. But when all-out hosing, I think I got the tightest spreads with the 19C. I would attribute that to how the 19 frame fits my hand better than the 17 frame. And the fact that the 19C flips a miniscule amount less than the unported 19. |

So it would seem the earlier posters were correct. The 9mm "C"s are nowhere near as dramatic in muzzle flip mitigation as the heavier-duty calibers. Now I'd REALLY like to try a 20C. I'm kicking myself now for not buying a NIB 20C last month for $525 OTD.

I would have thought my 125gr load would be hot enough to feel a difference, but the only time I noticed a significant reduction was when I was shooting weak hand only. |
