I have 2 Law Enforcement Trade In Glocks (a Gen 3 and Gen 4) That I personally shot 400-500 rounds through each and not 1 fail to fire or any issues. I was carrying mine daily until I switched to my Model 32 .357 Sig..I really like my model 22's and my model 23's..I don't see you having any issues with them...Welcome aboard!
A pic of the Glock-22 I picked up. I emailed Glock. They got back to me, and said it was manufactured in November of 2011. Other than the slide release there's very little finish wear on the metal. I'm wondering if this is a Lipsey's Exclusive with the gray frame.
For a while the PD trade in G22s were just too good a deal to pass up. The PDs flooded the market with them when they converted to 9mm. I like mine and got a G27 for EDC. I don't know of any reported issues with the Gen3 or Gen4. The 40 S&W is my "go to" round. I am an old 1911 man and I love the 45 acp also. I love that I can use G22 mags in the G27 and the fact that both can be converted to 9mm or 357 sig with only a barrel change. I think it is good sign that Glock is offering the G22 in Gen5.
I was in law enforcement when the gen2 & 3 .40s were probably the most widespread. Only issues I recall were the kabooms with the unsupported case barrels and a couple of one off problems.
I have a gen3 22 & 35 now. I use the 35 for uniform security work.
My G22 is a Gen 3. Several thousand rds. through it in the 23 years I have owned it. Has always worked well.
Took it to Smyrna when it was around 21 years old to get it checked out and to get a new recoil spring. They gave me a complete rebuild and 3 new replacement mags (mine were Clinton 10 rounders). Totally free! Glock stands by their products like few companies on earth!
I bought my G22 Gen 3 back when I retired. I had it 10 years while on the job. Probably 10,000 rounds or more through it. No FTF, FTE, any problems of any kind. All I've done since I've retired is replace the springs and the nights sights, which were getting dim. I think you'll love yours like I do mine. Extremely reliable.
