I'm looking for opinions on the following modifications as I'm purchasing a G29SF very shortly. 1) I like the idea of the Pearce +0 Extensions and was curious if anyone has had reliability issues with them on their 10rd mags? 2) Does anyone have the part # for the FACTORY Glock Extended Slide Release that fits the G29SF? A link to someone who sells the GLOCK brand part would be perfect. 3) Does anyone have the Glock Factory extended mag release on a G29SF and if so how comfortable is it when handling the gun? I have one on my Gen 3 G19 and love it but I'm unsure about on the larger framed G29 even though it is an SF model. Thanks in advance guys!
