The Difference Between Gen 3 & Gen 5 Glocks

[@glockstore]

What Gen. Glock do you carry?

[@GamingGrenade1]

Here in the UK, we can't even own/carry pepper spray without risking 7 years in prison because it is classed as a prohibited firearm... and people think _California's_ laws make no sense

[@DrDiff952]

Gen 3 G17 with Holosun 507c X2

[@Take-the-Ticket]

Gen5 48. Decorated with some of your accoutrements, Ameriglo sights, Tyrant trigger, and Talon grips. I need to get an angled hook thingy to put it the magazine catch, which I have. Just can't put it in yet...I will put in your Tungsten rod soon. I really enjoy your products and videos :)

Was just researching this a couple days ago. Buddy of mine who passed away 3 years ago let me shoot a Glock 19 and Glock 26 gen 3 before he died. I really loved how those pistols handled and wondered if the Gen 5 was a worthy upgrade.

[@Jordan-ql6tm]

Honestly I just stick with gen3, just preference npt enough changes to be worth an "upgrade." I like the finger grooves that gen5 removes, and I don't want to use a pos adapter plate which have always been common failure points I'd rather have a custom milled cut for my chosen specific optic and ride as low as possible. Plus a gen3 is usually when I've search a little cheaper, since I'll likely upgrade a few parts anyway why pay more?

[@ballsack8937]

Gen 3 are probably the best that Glock has to offer in terms of field proven reliability and aftermarket support.

the spring system for the sear was also redesigned between the gen 3s and 5s. Gen 3 has a much simpler version with it only having one parts for the spring system, the new gen 5s have three different parts that interact with the spring to make the sear move which while does give a better trigger feel that Glock calls their " marksman trigger ", it is less reliable.

[@rtz549]

[@johnholder9062]

Practicing triple taps last night gave me pretty consistent ftf issues with my 19x. Everything is oem Glock. Hopefully I can figure out the problem soon.

What happened to gen 4 springs?

[@ColonelCarnage]

My Gen 4 41 trigger spring got messed up. Gen 5 trigger setups are way better.

[@Cortezuma]

Gen 5 trigger is a huge improvement. Otherwise though, gen 5 tolerances are tighter… which is good but actually generally reduces reliability. However, I’ve had zero issues with numerous gen 5s and expect them to continue that way

Alaska, Montana, and Wyoming had the highest estimated gun sales per capita in 2022. In 2022, gun sales rose year over year in only three places: Iowa, the District of Columbia, and Oregon. So far in 2023, Texas and Florida lead the nation in total estimated gun sales, making up about 14% of all guns sold nationwide

[@uclajd]

Per capita dude. That doesn't address which state sells the most total number of guns. And California sells less that it would because of its handgun roster law (all new guns are not legal to sell), and 30 days between purchase rule.

I have a Glock 27 that is referred to as the gen 2.5. It has subtle differences from the gen 3 such as a smooth front strap with finger holds instead of the knurled front strap as you show in this video.

California is not the only State with a 10rd magazine limit. I am from NJ. I just ordered a G20 SF gen3. I assumed I couldn't go wrong with a Glock. Most of the videos and info I can find about it say. The barrels are bad and the guns explode quite frequently. I don't think I am going to accept delivery. I'll send it back and eat the re-stocking and shipping fees. I am going to try and look past the name and find a quality and reliable 10mm.

This might still be confusing to some. I have a Glock 26 which i purchased around 1998-1999.

[@kentwilliams3326]

I am concerned. The locking block pin came into being when the Glocks were tested at Aberdeen Proving Ground for the U.S. Border Patrol. The Glock 22 and 23 test weapons (3 of each model) catastrophically failed between 6,000 and 8,000 rounds of the 10,350 reliability / durability tests at Aberdeen. Subsequently Glock added the locking block pin and, as far as I know, that cured the problem. Glock, for reasons unknown didn't submit the modified Gl22's and 23's for our best and final offer tests. (Note: The tests at Aberdeen were conducted in 1993, 1994, and 1995.) When I saw that the Gen 5's did not have locking block pins I wasn't concerned because the non-locking pin series had successfully fired many thousands of rounds, far surpassing 10,000 rounds, but when I saw the Gen 5's being chambered for more intense cartridges I became concerned.

[@gsmithy7995]

I actually found a difference on the 17s the locking lug on Gen 5 will not allow to be used on Gen 3 it leaves a considerable gap on the recoil spring barrel to slide interface using a Gen 3 guide rod

I’ve owned and carried a Gen 2 G17 since 1992. I’ve put over 30,000 rounds through it over the decades. It’s unmodified and fully original. I’m not interested a red dot sight, but I am sorta interested in mounting a light to it. I’ve seen adapters that allows a light to be mounted where a light is mounted on the Gen 3 forward. Any recommendations on an adapter?

[@JR15A2]

I bought a G19 as my first handgun right after the model launched in 1988 and a G17L shortly after that. I keep those for sentimental value, but I've bought and sold countless others in all calibers and generations since then. I recently upgraded from a G19 Gen4 to a G19 Gen5 MOS and added a Holosun SCS optic and a Streamlight TLR-8 AG laser/light combo. It shoots great, but I'm still on the hunt for the perfect holster for it. After owning, shooting, and servicing examples of almost every Glock pistol made in a professional capacity over the past 35 years, I firmly believe the Gen5 models are the best so far. I wonder why some people are stuck on the Gen3 models. I'd pick a Gen4 or Gen5 over a Gen3 just for the improved dual recoil spring assembly, especially in any caliber hotter than 9mm. I never modify mine except for maybe sights, lightly polishing certain internal parts to smooth out the trigger pull and replacing recoil spring assemblies at the recommended intervals. I've seen too many people dick up a perfectly good Glock trying to play adult Legos with them. That might be ok as a range toy for some people, but not me. I've yet to see any adapters I'd trust to attach a weapon-mounted light securely on a Gen2 G17. Finding a compatible holster might become an issue if there was such an animal. If I were you, I wouldn't necessarily kick the old girl to the curb, but I wouldn't hesitate to bring home one of the new and improved models to keep her company. Also, it sounds like we could be close in age, so I'll mention that I was slow to get on the pistol optic train like a lot of folks from my generation, but I eventually realized that my eyes weren't what they used to be, so I was glad I started buying the MOS models when I did so I could attach an optic to them easily once I was ready.

[@JR15A2]

The G26 isn't the best to compare since all Gen3 models except the sub-compacts use the old single-spring recoil spring assembly. In contrast, all Gen4 and Gen5 models use the more desirable dual-spring assembly, one of the most significant improvements they've ever made to the original design.
