Locked up my G33, Please help!

[BSA70]

I did a barrell swap, .357 to a .40 lone wolf. Went to the range, tried to rack the slide to load and found out the gun is locked up. I can pull it back about an inch and that is it. Not far enough to engage the little slider so I can take the slide off.

What do I do? I see some recessed pins, will knocking them out allow me to get the slide off.

I must have not installed the recoil spring properly.

The gun is locked up? Sorry, I do not understand?
You need to make sure the chamber is clear. Rack the slide back, even an inch will work. Pull the trigger. Pull down on the slide lock lever to release the slide. If you can not get past this simple part you need to return to the shop where you purchased the gun and get some help.
