Advantage Arms .22 LR Conversion Kit for the Glock 21
The main intent of this acquisition is for the significant cost saving achievable while still being able to use
one of my favorite guns. This kit was purchased on line for a cost of $245 shipped with a little help from
a 10% discount from the distributor.
The Glock 21 is chambered for .45ACP and at the time of writing the cheapest on-line ammunition I
could find was $.34 per round of Sellier and Bellot 230 gr. FMJ ball nose ammo purchased in lots of 50.
Winchester White Box .45 ACP 230 gr. Ball nose is .36 per round purchased in lots of 500. The .22LR is
on the order of more than four times cheaper at $.07 per round of CCI 32 gr. Mini-Mag ammo purchased
in lots of 500. There are many other .22LR ammo manufacturers out there whose prices are even less,
however I’ve found that CCI ammo has provided me with the best consistency and reliability during my
short duration as a shooter and therefore favor their ammo a little more.
Typical days at the range, if I’m by myself I usually spend about one to two hours shooting. Depending
on how quickly I reload and if I’m just there to make noise or actually accomplish something I could fire
upwards of 100 to 200 rounds of ammunition. To put it into perspective, here is an estimated cost table
of how much it costs for me to shoot per day:
.45 ACP S&B $.34 .45 ACP WWB $.54
.22 LR CCI Mini-Mag $.07
It will take me about 1000 rounds to recover the costs of this conversion kit, assuming one gets the
same amount of pleasure popping .22s as they do .45s and I’ve got my math right!
