Flush fitting plugs for models G17, G18, G19, G20, G21, G22, G23, G24, G25, G31, G32, G34, G35 These do not fit the SF models.............I did just find out that is will fit a model 37 and 38 which are 45gap models. Black Plugs are $4 each OD plugs are $5 each I ship usps in a padded envelope with delivery confirmation for $2.00 unless your order 10 or more, then shipping will go up a little. So PLEASE remember, add $2 to your total to pay for the shipping. so if you want 1 black plug, send $6, 2 will be $10 and so on. 1 OD Plug will be $7 and 2 will be $12 and so on.
