RE: Shrike 10 Kit
When building the Shrike, read the instructions three times and be SURE you understand what they ask you to do.
The ones I built had OS .32s shoehorned into the front and they were ballistic! The .32 is probably actually more powerful than the LA 40.
I agree with the buzzard, look at some of the small .40 kits like the Uproar.
