Starting off with a video from a guy who works with Crosman to make their guns better. This is a Crosman airsoft gun - but before you say it is complete garbage consider what it has to offer.

$60 on Pyramid Air, use the coupon code Nutnfancy for $6 off.
Pros:
Metal Slide
Strong plastic grip
Field Strippable
Hop up system
You can take everything out of the slide when field stripped.
Slide locks
Nice capacity magazine (26)
Advertised FPS at 320-340 (likely less)
Cons:
Somewhat unaccurate
Blowback will just fall off when the slide is out
Lose items - Explained in the video
Safety is horrible
Ugly look - A "bad"? looking Glock 17?
Finding magazines is hard - I couldn't find any but I only looked for about 10-15 minutes.
Hard on the C02 - Unknown amount of shots, but I would guess around 100-120 (Around Average)
