I'm still debating if I like the Knoxx Gen2...   

When I did the 'how-to' video for installing this forend, I said I do a review of it after testing it in the field (if you will...) and here it is.

Pros:
-Cost (I paid $25)
-Ease of installation (see previous video)
-Modularity (accepts rails and all the accessories that accompany them)
-Solid lock up (very little to no play at all)
-Design allows easy manipulation of the action, more so than the OEM forend
-Appearance (just plain looks good on the shotgun)

Cons:
-Creates wear marks on the barrel/mag tube.

Here's the review video:




All in all, I love this forend.  It's one of those products that makes you say, "Why didn't anyone make this before?"    I just ordered a few more to replace the forend on all of my 870s.

QuoteOne thing to note, I believe the Blue Label guns will come with (3) mags for standard and compact, non-Blue label should come with standard (2) if it is the same as previous models.

It's my understanding that all Gen4s come with 3 mags.   That said, I only buy blue label Glocks so I'm not an expert on this...

Thanks for the kind words.

Couldn't get the video to embed in the OP, not sure why...

Being someone who teaches groups of new shooters from all different backgrounds frequently, I often get the question, "Which gun should I get?"    My answer about 80% of the time is the Glock 19.   There's a reason it's the most popular handgun in America––-it's a great gun that can fill just about any role.   

Pros:
-Reliable (I address the recent issues in the video below)
-Accurate (more accurate than 99% of the shooters that own one)
-Durable (many reports of these guns going over 100,000 rounds with only a spring change)
-Easy to maintain
-TONS of aftermarket support
-Accepts 15, 17, and 33 round factory magazines
-Small enough to carry, but with a 15 round magazine
-Glock's customer service is second to none
-Durable finish
-Cheap replacement parts, should you ever need them
-Low Bore Axis resulting in a relatively soft shooting gun
-Easily modified to fit the shooters' preferences
-Requires very little cleaning/lubrication to run reliably (that said, clean your guns!)

Cons:
-Recent erratic ejection issues (I had one of these guns but Glock replaced it free of charge)
-9mm Glocks are susceptible to 'limp wristing'  (most semi-auto 9mm guns are however)
-Comes with a serrated trigger (I'm not a fan)

Here's a brief review video with some shooting at SD distances (12m), longer range shooting (40m), table top with disassembly and size comparison with all the 9mm Glocks/Caracal C/M&P9 Pro, and some chronographing with popular carry/defensive loads:

Welcome to the forum.  Your video has been well studied here and is much appreciated.

I too am interested in getting a gen 4.

Thanks for the support gentlemen!

First post here so I figured I'd start out with a bang 

Many devout fans of the 10mm love their Glock 20, myself included.    So when I heard the Generation 4 version was released, I jumped at the chance to pick one up.   I really like the Gen 4 grip on my other Glocks and I thought it would be especially helpful with the recoil of some hot 10mm rounds.   Turns out I was right.

I ordered the gun the day it came out and had it in my paws the next day.   I cleaned it, lubricated it to specs, turned the rear sight around (I don't like the Glock sight picture), and patiently waited for the weekend to put some rounds through the beast. 

Pros:
-Glock grip angle helps absorb the 10mm recoil (one man's opinion)
-Cost: many other 10mm pistols sell for double what the G20 sells for
-Accuracy: the gun is more accurate than I am
-Positive ejection with both hot and weak loads
-Easy to maintain
-Gen 4 grip surface helps keep a firm grip on the gun, even when your hands are sweating
-Low bore axis helps tame the recoil
-Lots of aftermarket support (holsters, sights, ect....)
-100% reliable so far

Cons:
-new to the market so heavy recoil springs aren't yet available
-the finish isn't the old glossy Glock finish of a few years ago so finish durability is unknown

Heres a video I did to show the firearm in action.  I do some shooting, demonstrate the ejection pattern with hot ammo, a 15m group, table top review (with part numbers), and some chronograph testing.
