In case you already purchased the trigger cover, but started having the issue with spring guide stopper falling out, you can just buy this upgrade part.
This upgrade kit only ships with the outer shell. You need to keep the small plastic piece which goes around the trigger for this to be useful. You may need to do some small sanding with 500 grit sandpaper in case of some dimension differences.
1x Extended trigger cover shell
