Handguns, as others have said aren't a good idea.

But some people like challenges so here's a list of things you can try:

• r17 (looks great but still in "beta" although looks almost complete, not an easy build but looks reliable)
• null 22 (or not-a-glock, which looks less reliable)
• el ratto
• beach pigeon
• beagle
• make a 22lr 19911 with a mix of these files: https://guncadindex.com/detail/ok-boomer-1911:b https://guncadindex.com/detail/FossWerks_3D11_Beta:0 https://guncadindex.com/detail/1911-22LR-MAG:0 https://guncadindex.com/detail/22-1911-verson-1.2:8 (needs work)
• yeet22h (+ compact version)

Easier first builds (PCCs mostly)

• decker 380
• urutau
• fgc9
• rogue 9
• rebel 9
• FGCz9
• hd22c and plastic blaster's other builds
• kaewon's builds
• Cease and Desist

Harder:

• mp22k

Edit: i forgot: HW4 Mega Pistol !!
