Disclaimer: I am not connected with Apex in any way. I know it is unusual to post new after-market items on this Forum, but for SD9/SD40 owners, after-market items are slim pickings and this is the first new thing I've seen come along for the SD's in a long time. Maybe its not new to everyone, but the email made it sound "new" to me, so I am passing it along.

The kit appears to be the Apex enhanced trigger plus the Apex SD spring kit, with the addition of an Apex Sear Spring. See picture in thumbnail.

The Apex webpage also has direct links to Apex's videos on SD9/40 slide disassembly and frame assembly/disassembly, which may be of use to folks here even if you don't buy the new kit.

It would be interesting to see if anyone has installed this kit, and what the results are for your SD9/40.
