This NP3'ed OEM Glock™ 5 lbs Connector (PN SP00343 is favored in most non-slimline Glocks due to its profound wall although slightly heavier than the DOT connector. Pair it with our Extra Power Trigger Spring for a lighter, predictable break that has a more defined wall than our NP3'ed OEM DOT Connector. Also provides great results with the GPT.
