Why particularly non-blowback? Presumably for more POWER...
As our strange looking @heroshark stated, the MK23 (several makes) is generally regarded the standard.
Keep in mind its very large with the suppressor and a blowback is arguably more fun.
Yes, the power is higher than most blowbacks but the AAP01 is a good contender and range/accuracy doesn't just depend on power.
Also as @Cr0-Magnon said, you don't actually use them that much really.
