I finally managed to get a Lobos Trigger and I'm trying to install it on my VP9SK. Every thing was going well until it came time to remove the "Stop Bolt for Trigger" which is Part 9 of the Exploded Diagram in the VP9 Operator's Manual. The Bolt (or Pin) does not go all the way through the frame and can only be pushed out from the inside. Since it can only be accessed by reaching down into the locking block it makes it a bear to get any pressure to push it out. I have tried using prying it out with round punches, screw drivers, etc. The only way I can see to push it out is by prying against the opposite side of the locking block. So far I cannot get it to budge. Is there something I should be doing that I am not? If anyone has ever removed this Bolt please let me know how you did it. I have done quite a bit of work on firearms including building several AR's but nothing has ever stumped me like this and caused me to say so many bad words. Advice is greatly appreciated.
