Hi guys, I just got my new 21SF frame from Glock last week. It has the standard mag release in comparison to the ambi mag release that was on the original frame that started to dump mags recently. I had a 3.5lb. connector that I liked very much and I had installed in the original frame and removed it and re-installed the original connector when I turned back in the original frame to Glock. I was wanting to install the 3.5lb. connector into the new 21SF frame. I have the standard Glock dis-assembly tool that I use to do this. I had no trouble removing the pins before in my original frame. I went to push the locking block and trigger pins out in my new frame to begin the dis-assembly process to change the connector and they wouldn't budge! It's almost like they are put in there with Loctite. I did not and will not use a hammer to do this. What could be the problem here? Is this just new and tight and might need to be shot a little loose with a few range sessions or is there something else that might be causing this. Should I place a drop or two of say Kroils Oil onto the pins heads overnight and let it sink down into the binding areas of the pins to loosen them up? The rear trigger assembly pin in the backstrap area moves freely and ok when pressed with the Glock tool. Thanks.
