M1911 Inconsistancies (KWA/KSC)

[Strelok]

Alright, I just seem to be having a plethora of problems with my guns lately.

I have a KWA/KSC m1911 from them, Metal Slide, plastic frame, pretty sturdy overall. Lately i've been seeing a lot of... Inconsistancy. my slide will lock back for no reason through some shots, And the gun 'will' cycle, but doesnt seem to want to shoot the BB's out the barrel, They just pile up inside the barrel, and fall out one by one. Though, sometimes, I'll get the first four or five shots out before the BB's pile up, (14 round magazine, mind you).

Any help would be appreciated. Thankyou
