Go with the Glock 35. You can load minor 40 for production and then add some Dawson mag base pads and a magwell for limited. The Glock 34 is the most popular gun in production class. The Glock 35 is the most popular polymer pistol in limited division.
You will get more back out of a 35 than a 22 as well if you ever decide to sell.
Here a picture if my Glock 35 limited gun.
