Advantage Arms Glock 22 caliber conversion kit

On my way home yesterday I stopped in at the local Pawn Shops to pickup one of the stripper Areo AR uppers they had gotten in. While I was there I had a look around. I spotted an Advantage Arms 22 caliber conversion kit. It was used, a little dirty, but priced $165. I didn’t have a close look at it but I thought it would be nice to have.
While at work today I started thinking about the conversion kit. It was for a Gen 3 gun and would fit my Glock 22. I looked up what a new kit cost, $299.
But then that squirrel in the back of my head started running around and got me to thinking about how cool it would be to pick up a Polymer 80 Glock 17 frame and use it to build a 22 pistol. So on my way home today I stopped in at the shop and had a good look at the conversion kit.
It appears that it was another victim from the 2016 Flood. There was some rust on the guide rod and a little on the barrel, but the bore was bright and there was an extra mag.
We went back and forth on the price and ended up at $100 out the door.
Here are the pics I took when I got home.


I took it apart and cleaned it up. There’s just a little pitting on the guide rod and a spec or two on the barrel. Here it is on my G22 frame. My son, Austin, asked my to get a Polymer 80 OD Green frame for the build so, I think that is what I will do.

I have a soft spot for 22s in general. I picked up a Kimber 22 conversion kit for my 1911 fifteen years ago. About 12 years ago I bought a stripped Riock Island frame and made it the dedicated frame for the Kimber kit.
It has seen a lot of use.
My son put those old Pacmyer combat grips on it.

I ordered a spring replacement kit an an extra mag spring on Monday and it arrived today. Four days, not bad.
The firing pin is very close to a Glock and was easy to remove and put back in the guide rod and spring were a simple swap out.

The old mag springs were pretty rusty, but everything cleaned up and the new springs work much better.


I’ll bring it to work tomorrow and see how it works.

When I shot it last week I had FTE & FTE problems.
Now the kit appeared to have stayed wet in the carry case for some time. The guide rod spring was rusted pretty bad and I had not taken the mags apart.
The spring replacement kit along with the extra mag spring was only $27 with shipping.
I fired it this morning when I got to work and it shot great without any issues.
I think this thing is going to be a lot of fun
The plan now is to by a Polymer 80 17 frame to build to give the kit permeant home.

Well the plan was to get a Polymer 80 G17 frame in FDE, but the wholesaler that the gun shop orders from was out of FDE frames. So I had him order me a OD Green frame. I know that I could have ordered from somewhere else but not for $100.
I stopped by on my way home today and picked it up. $100 out the door.


I ordered a lower parts kit today. If it comes in by Friday, I’ll have it built this weekend.

My lower parts kit arrived yesterday, but with having to finish painting the house and cutting the grass, I had to wait til this morning to put things together.


This was my second Polymer80 build. The slide fit great and moves very smoothly on the frame. I’ll take it to work tomorrow and see how it functions



The frame is darker then the new color on the house.

I fired the gun yesterday. The first mag with five rounds worked great. I loaded another five rounds and the first two rounds I had FTF. The gun was a little dry so, I added some oil and loaded ten rounds in the mag. The first round I had a little trouble with feeding, but after that everything fed great. I put another 30 rounds through it with no issues.
