KSC Glock 19 upgrade metal slide

[KND]

Hi ! I just upgrade my KSC Glock 19 metal slide but It doesn't shot well like my plastic slide. The slide won't push back to original and the gun can't fire. I just wonder do I need to upgrade the spring as well for this metal slide and chamber. After put new slide, the gun look very weak when cocking and doesn't push back to original very fast like the plastic slide. I really have no idea why. Any helps would be appreciate. Thanks in advance.

I got two extra magazines along with this gun but I can't insert the BBs inside it. Look like the hole is pretty small for 6 mm bbs. Any idea everyone ? Thanks in advance.

Cheers !

yea, you definitly need to upgrade the recoil, and possibly the hammer spring for more output of gas when firing.

The KSC G19 using the generic metal slide *should* be able to function fine with the stock recoil spring, but I'd definitely upgrade the recoil spring anyways to increase blowback speed

Second the requirement for a stronger recoil spring/guide (they come as a set, contact Jugglez).

As for the enhanced hammer spring, it does fuck all except make the gun more reliable in hotter weather due to the increased pressure of propane in a mag.
